The long, slow-moving lines at many polling places Tuesday were just the latest voting problem in Florida, since the hanging-chad recount of 2000.

From Orange County to south Florida many people said they had to wait several hours Tuesday.

Outside the Lake Nona YMCA, 150 people were still waiting to vote at 9 p.m. It was the same story in south Florida, and even President Barack Obama acknowledged the problem as he thanked Americans for voting.

"...whether you voted for the very first time or waited in line for a very long time -- by the way, we have to fix that," said Obama.

So what is to blame for the late, long lines? Orange County Supervisor of Elections Bill Cowles has a list of challenges, including high voter turnout, an unusually long three-page ballot and scanners that only process one ballot page at a time.

"All of the supervisors will take a look at how we staff for presidential elections in the future, but we don't know what the factors are. Will we have three ballots? Will we have long ballots?" Cowles said.

Cowles said it's tough to troubleshoot an election that only happens every four years, because there are so many factors he doesn't control including the length of the ballot and the amount of voter turnout at new and growing precincts. He said convincing local lawmakers to purchase more voting equipment is tough because it's a big expense for something that may only be needed for presidential elections years.

A spokesman for the Secretary of State's Office in Tallahassee said one solution may be to encourage more voting by absentee ballots but he admitted their office is aware of the problem.

"I think the long lines we saw yesterday would be something we take a look at it, whether there's anything we can do at state level," said the spokesman.

Is the solution to add a few more days of early voting? Cowles said it's not so much the number of days but the capacity of the facilities where early voting is held that could make a difference.

Cowles said he wishes rather than being limited to government buildings like libraries and city halls that he could rent out a larger nongovernmental facility that could host a larger number of early voters and more voting equipment.
